Various mechanical operations can be considered for the separation of chromite from olivine as magnetic or gravimetric separation [8,9]. Flotation of chromite, based on surface phenomena, has been ...
SEPARATION OF CHROMITE FROM OLIVINE BY ANIONIC COLLECTORS Chromite is concentrated mostly with shaking tables and spirals. Flotation can be considered as a leading process to beneficiate the fine chromite which cannot be enriched by gravity separation. Because of the complex nature of chromite and olivine which is the most abundant adjoininig

Ultramafic rocks and their related soils (i.e., serpentine soils) are non-anthropogenic sources of metal contamination. Elevated concentrations of metals released from these soils into the surrounding areas and groundwater have ecological-, agricultural-, and human health-related consequences. Here we report the geochemistry of four different serpentine soil localities in Sri Lanka by coupling ...

The Gora sample consisted primarily of chromite and olivine, changing to serpentine with a small amount of orthopyroxene. The olivine ranged in color from green to yellowish-brown. The chromite is liberated essentially in the minus 100-mesh fraction; however, a small amount of chromite remains locked in the minus 325-mesh fraction.
Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates. A good knowledge of the flotation behaviour of chromite and the establishment of conditions for its selective separation from the gangue minerals might help the future exploitation of chromite deposits.
The major Indian chromite deposits are located at Sukinda region of Orissa state. The depletion of high grade ore resources and having a variety of gangue minerals such as goethite, serpentine, olivine and talc, etc., has lead to the utilisation of lean ore after beneficiation. Further, ample

The efficient separation of pentlandite from serpentine remains a challenging issue in the processing of nickel sulfide ores. In this study, selective magnetic coating-magnetic separation was employed to separate the pentlandite from serpentine with adding NaOL as a coagulant, which is different from the conventional flotation.

methods have often been used based on density differences between chromite and gangue minerals. Heavy medium separation and jigs in coarse sizes, spiral, shaking table, magnetic separators, multi gravity separators, and flotation in fine sizes (≈ 0.5 mm) are the well-known and widely acceptable methods (Burt, 1987; Guney et al., 2009).
chromite (recovery of 95.1%) could be separated from serpentine (recovery of 3.2%) whereas it could not be separated from olivine. The best chromite concentrates containing 42.1% Cr 2 O 3 were obtained with a 76% recovery from a synthetic mixtures of chromite and serpentine under optimum test conditions, that is
chiefly serpentine and olivine. When grounded to-100µm the serpentine dominated the fines, chromite the medium particles and olivine the coarse. Strongly alkaline pulp (more thanpH10) was used, with sodium oleate and oleic acid to float the serpentine. The pulp was then rendered acidic (pH3) and chromite was floated with 0.75lb/ton of
While pytite, serpentine, marmatite, chromite, and sphalerite, could be activated by Cu(OH) 2, it is still unfavorable for separation by flotation, especially under strong alkaline conditions. In order to improve this mechanism, ammonium salt and ammonium metal complexes, two other important flotation reagents, are widely used in the ...

Chromite ores are usually concentrated by gravity concentration techniques based on differences in specific gravity between chromite and the common associating gangue minerals and rocks such as serpentine and olivine. Jigging has been used to upgrade a California chromite ore containing 18.1% Cr 2 O 3 to produce a concentrate assaying 43.5% Cr
